Backyard Biology - Other Critters

This page is a "catch all" for all the backyard critters which are neither birds nor insects. These critters were all found in our yard (back or front) or, in some cases, inside the house. Some of these critters are cute and furry; some of these critters are hairy and scary! In either case, enjoy peeking through some of the amazing fauna that's probably in your backyard as well.
